Yes, and according to Nvidia if you have a MP system, i.e multiprocessor system you can currently do the following:
APIC can be disabled on smp kernels with the "noapic" kernel boot option;
this forces interrupt processing to legacy PIC mode which limits interrupt
processing to the first CPU.
BTW, I wrote a HOWTO about installing the card on Debian 3.0 found here:
